[Synthesis]

Excellent regio- and stereoselectivity during nitrile addition to dienylium-Fe(CO)3 can be achieved with perchlorate salts, allowing the preparation of the 1-oxo- and 3-oxo-2-azaspiro[5.5]undecane ring systems[1]. tert-Butyl 3-oxo-1-oxa-4,9-diazaspiro[5.5]undecane-9-carboxylate has similar structure.
